## Description

Worried about skipped meals, restlessness, or a lean frame? This weight-focused daily cat thyroid aid provides composure and appetite support for picky eaters, encourages regular mealtimes, and helps maintain a healthy body composition. It fits naturally into everyday cat health routines alongside other daily cat supplements & vitamins that cat parents already use. If you notice symptoms like restlessness, unexplained patchy fur, more litter box trips, shorter or skipped meals, or a cat that looks a little too slim, finding the right solution and using it consistently matters. When it comes to comparing a paste-style weight gainer for cats, strong-flavored or heavy calorie-rich cat weight gainer diets, these tiny, quick dissolve pellets make it easy for your cat to eat every day and feel better No fuss, easy to give. Each bottle includes 400 odorless, tasteless pills you can hide in squeezable cat treats, or a pill pocket, add to wet or dry food, or crush into a fine powder and dissolve in water. No sticky gels, no chasing, just simple dosing that works for seniors, rescues, indoor and outdoor cats, and selective or stressed eaters who need dependable mealtime habits. This natural, routine-friendly option helps senior and hyperactive felines maintain balanced weight without relying on a high calorie cat food weight gain diet or harsh prescriptions. It’s also gentle on the tummy, so you won’t need a cat laxative constipation relief product to stay regular. Use it alongside your existing cat vitamins and supplements for optimal support. Since consistency is key to achieving your cat health goals, make this solution a key part of your feline thyroid support, which incorporates easily into your daily cat supplement routine to help keep your cat’s care simple, organized, and consistent. Made with a gentle, plant-based approach and crafted by pet parents for pet parents, this formula reflects our commitment to quality. BestLife4Pets is a brand you can trust, known for holistic, made in the USA cat health supplies that support practical, real-life routines centered on steady eating and a healthy body condition.

Review: Yes Yes Yes — Great Product! - Update 6/20/2023: About one week ago we had to give our cat some methimazole to stabilize as he was losing weight and seemed a bit jittery. He was giving off that “espresso shot look” again. …Now we are alternating the BestLife with the methimazole. Update 5/31/2023: Our cat is doing great! The main factor was to maintain weight and the hyper activity. We give him 3 pills inside of a pill picket by morning and 3 pills again at night. Sometimes we miss doses by accident, but he is doing well! Update 5/6/2023: Our cat is beginning to lose weight and seems more hyper so we upped his dose. His weight is usually around 14-16 lbs. we adjusted to three doses per day (2 pills each). 6 pills/day total. Update 4/26/2023: This product has surprisingly been great! We have skipped some evening doses and he acts the same. We have decided to dispense two tablets (based on weight) in the morning and one at night (instead of another two). He is maintaining his weight and everything is normal/ as usual! He no longer has loose stool after about 1.5 weeks. ————- My 14 year old orange tabby (14-16lbs) was diagnosed with hyperthyroidism two years ago after losing weight far too fast, constant hunger and looking like he drank 8 cups of espresso daily… needless to say, our vet did some bloodwork and he has been on methimazole ever since. More recently, I have carefully considered (after thoroughly reading about pharmaceutical drugs) that I highly prefer to go the natural route given the damaging side effects any Rx can potentially have on animals/humans. These little tablets are a God-send! They’re so easy to pop inside of a pill pocket. Thus far, he is on week two and he takes two of these tiny tablets in the morning and another two in the evening. So far, so good! No issues with them going in the pill pockets, either. He is calm, sleeps normally, and eats normally. It was a quick transition from the methimazole. The only negative is a loose stool. I am hopeful it will regulate soon, but only time will tell. I also read someone gives their cat three doses per day. *keeping that in mind for later down the road* Two doses of two tablets per day works great for now. Each bottle is 450 tabs. We are very thankful for this natural product!!
Review: Seems to be working well for weight gain/appetite - I pair this with my cats thyroid meds. Twice a day! He’s looking healthy and back to his old self with weight gained. Idk if it’s solely his thyroid meds helping or with this medicine paired with it for results. I have had no issues with it! I do recommend paired with thyroid meds.

### ⭐⭐⭐⭐⭐ Was skeptical, but happily surprised
*by L***A on October 23, 2024*

I read a lot of reviews about their cats dying after this medication (which I wondered if the cat was too far in for treatment before taking this medication), reviews that the product was homeopathic and wouldn't work due to no placebo effect with animals and some reviews from people who were recommended this by their vet for pets with sensitivities. I didn't want to take my cat to the vet as she's already anxious and easily stressed and she hates the vet office to the point of shaking when she's there. She's 12 years old and I recognized the beginning of hyperthyroidism. She's always been a small cat, never above 6 pounds, so the weight loss was hard to tell on her. Her back fur kept balding from overgrooming and her nose fur started to go which really got me paying attention. I noticed she was peeing more often and drinking a ton of water, her sister had this issue and she ended up dying not long after I realized the issue so I started looking into treatment at home besides home cooked meals. I started this cautiously, 1 pill for about 7 days just to see how she reacted to it. She was fine, no real issues. I finally started the 2 pill recommended dosage after establishing she wasn't going to have a reaction to the medication and within about 2 weeks I noticed changes already. She stopped scream meowing constantly, she was less aggressive about food and she toned down on the water. I have started giving her 2 pills at the same time every day so I don't forget and she's doing well with that for the last 1.5 weeks. It's been probably near a month and her hair on her back is growing back, the nose is unchanged, but her weight is back to normal and she's back to playing with my other cat rather than lashing out at her randomly. You get a lot of medication in a glass bottle so that's an amazing sign of quality and the results have sold me. This won't cure her, but it will help her stay herself until it's eventually her time to go and I'm grateful for the time this medication is giving us.
